Salk Institute for Biological Studies Salk researchers discover a master gene responsible for sleep and wake cycles, offering hope for a drug that could help reset sleep Scientists at the Salk Institute for Biological Studies have identified a gene that regulates sleep and wake rhythms. The discovery of the role of this gene, called Lhx1, provides scientists with a potential therapeutic target to help night-shift workers or jet lagged travelers adjust to time differences more...

Warwick University Research led by the University of Warwick’s Systems Biology Centre and Warwick Medical School in collaboration with groups in Nice and Rotterdam has been able to demonstrate how the cycle of cell division in mammalian cells synchronises with the body’s own daily rhythm, its circadian clock. The study not only helps to explain why people with sustained disrupted circadian rhythms can be more susceptible to cancer, it may also help establish the optimal time of day to...

FECYT - Spanish Foundation for Science and Technology A possible pharmacology objective for chemotherapy Patients receiving chemical treatment for cancer often suffer fatigue and body weight loss, two of the most worrying effects of this therapy linked to the alteration of their circadian rhythms. The circadian system, better known as our biological clock, is responsible for coordinating all the processes that take place in our organism. If it does not function correctly, what is...

Fruit flies are pretty predictable when it comes to scheduling their days, with peaks of activity at dawn and dusk and rest times in between. Now, researchers reporting in the Cell Press journal Cell Reports on April 17th have found that the clusters of brain cells responsible for each of those activity peaks—known as the morning and evening oscillators, respectively—don't work alone. For flies' internal clocks to follow the sun, cooperation is key. "Without proper synchronization,...

You've switched to the night shift and your weight skyrockets, or you wake at 7 a.m. on weekdays but sleep until noon on weekends—a social jet lag that can fog your Saturday and Sunday. Life runs on rhythms driven by circadian clocks, and disruption of these cycles is associated with serious physical and emotional problems, says Orie Shafer, a University of Michigan assistant professor of molecular, cellular and developmental biology. Now, new findings from Shafer and U-M doctoral...

VIP Treatment For Jet Lag

Washington University in St. Louis A brain chemical that desynchronizes the cells in the biological clock helps the clock adjust more quickly to abrupt shifts in daily light/dark schedules such as those that plague modern life A small molecule called VIP, known to synchronize time-keeping neurons in the brain's biological clock, has the startling effect of desynchronizing them at higher dosages, says a research team at Washington University in St. Louis. Far from being catastrophic,...

Gladstone-led study sheds light on molecular basis for metabolic health and disease Inside each of us is our own internal timing device. It drives everything from sleep cycles to metabolism, but the inner-workings of this so-called "circadian clock" are complex, and the molecular processes behind it have long eluded scientists. But now, researchers at the Gladstone Institutes have discovered how one important protein falls under direct instructions from the body's circadian clock....
